HAND OR WIRE vise.

SPECIFICATION forming part of Letters Patent No. 269,903, dated January 2, 1883.

Application filed July 18, 1882. (N0 model.)

To all whom it may concern:

Be it known thatl, SAMUEL B.-VVHITEHEAD, a citizen of the United States, residing at San Francisco, in the county of San Francisco and .State of California, have invented a new and useful Improvement in Hand or Wire Vises, of which the following is a specification.

The object of my invention isto give increased holding and pressing facilities to hand or wire rises; and the invention consists in making a hand or wire vise with arms, link attachments, stationary shaft, and loose ferrule or band, as hereinafter specified.

In the accompanying drawings, Figure 1 is longitudinal section of my improved vise. Fig. 2 is a side view thereof. Fig. 3 shows the inside of one of the clinching-jaws. Fig. 4 is a transverse section taken in the line 00 ac, and Fig. 5 is a transverse section taken in the line 3/ 3/- A A are the arms, and a a thejaws thereof. B is the shaft, made stationary and threaded outside and hollow inside, and b a broken space therein to show the hollow. G O are the connecting-links between the arms and loose ferrule. D is the handle; E, a solid ferrule threaded inside on the upper end of the handle, and e e the shoulders of such ferrule; I the loose ferrule or band around the solid ferrule of the handle, and H the connecting hinge or joint at the upper end of the shaft.

Similar letters refer to similar partsin all the drawings.

In using my invention I insert the wire or other material to be heldbetween the jaws a. at of the arms A A, and then turn the handle, and thus cause it to move up the threaded shaft B. The handle, moving up the shaft, shoves the connecting-links G C upward and outward, and this spreads the lower ends and .closes the upper ends or jaws of the arms A around the solid ferrule admits of the handle being revolved, so as to move up and down the stationary shaft, as above mentioned.

The advantages of my invention are that its link motion greatly increases the holding and pressing power of a hand or wire vise, and, having no thumb-screw in the way at the upper end, it is more convenient than the ordinary hand or wire vises now in common use. It is also capable of being used as a hench-vise when enlarged and properly connected.

Having thus described myinvention, Iclaim as new and desire. to secure byLetters Patent- 1. The combination, in a hand or wirevise,of astationary shaft, arms, connecting-links, loose ferrule, and handle, substantially as described, and for the purpose set forth.

2. The combination, in ahand or wire vise, of the stationary th readed shaft B, arms A A, connecting-links C O, loose ferrule F, threaded ferrule E, and handle I), substantially as described, and for the purpose set forth.
